preact-refresh v0.4.1

Preact-Refresh

Experimental package

We are still fleshing out the details on how to go about this approach best for Preact, we'd love to give you the best reloading experience possible.

Note that now the refreshing component will dispose of its hookState to reload in case of added hook, ... this to ensure consistency.

Setup

npm i -s preact-refresh
## OR
yarn add preact-refresh 

Then add it to your webpack config by doing

import PreactRefreshPlugin from 'preact-refresh';

const config = {
  plugins: [
    new PreactRefreshPlugin(),
    new webpack.HotModuleReplacementPlugin(),
  ],
  devServer: {
    hot: true, // ensure dev-server.hot is on
    ...moreDevServerConfig
  },
  ...moreWebpackConfig
}

Uncertainties

• component altering lifecycles
• error recovery
• adding dependencies to hooks
• state-hooks ordering
• avoid triggering effects for added dependencies
• transition better from Functional --> class and other way around
• provide fallback if no hot modules/no preact modules (window.location.reload())
